Development of The Transparentwinged Plant Bug, Hyalopeplus pellucidus (Stal), A Pest of Cultivated Guava in Hawaii

The life cycle of the transparentwinged plant bug, Hyalopeplus pellucidus (Stal), was studied on guava, Psidium guajava I... Eggs were deposited in stems, flower buds, and leaf midribs and hatched in an average of 7 days. The 5 nymphal stadia were completed in an average of 14 days. The nymphs were anthophagous, and feeding on flower buds was necessary for normal development. Cage studies showed a direct relationship between feeding injury and the abscission of guava flower buds

Combined Pre-Supernova Alert System with Kamland and Super-Kamiokande

International audiencePreceding a core-collapse supernova, various processes produce an increasing amount of neutrinos of all flavors characterized by mounting energies from the interior of massive stars. Among them, the electron antineutrinos are potentially detectable by terrestrial neutrino experiments such as KamLAND and Super-Kamiokande via inverse beta decay interactions. Once these pre-supernova neutrinos are observed, an early warning of the upcoming core-collapse supernova can be provided. In light of this, KamLAND and Super-Kamiokande have been monitoring pre-supernova neutrinos since 2015 and 2021, respectively. Recently, we performed a joint study between KamLAND and Super-Kamiokande on pre-supernova neutrino detection. A pre-supernova alert system combining the KamLAND detector and the Super-Kamiokande detector is developed and put into operation, which can provide a supernova alert to the astrophysics community. Fully leveraging the complementary properties of these two detectors, the combined alert is expected to resolve a pre-supernova neutrino signal from a 15 M$_{\odot}$ star within 510 pc of the Earth, at a significance level corresponding to a false alarm rate of no more than 1 per century. For a Betelgeuse-like model with optimistic parameters, it can provide early warnings up to 12 hours in advance
